ADA4310-1ACPZ-RL

Overview

The ADA4310-1ACPZ-RL is a dual high-speed current feedback operational amplifier designed for broadband applications requiring high linearity and low impedance load driving. It features a 190 MHz bandwidth at a gain of +5, an 820 V/µs slew rate, and a differential output swing of 20.4 V p-p from a 12 V supply. The device operates on single or dual supplies ranging from +5 V to ±6 V. It includes power management with four modes controlled by CMOS-compatible PD0 and PD1 pins, reducing quiescent current to 0.65 mA per amplifier in shutdown.

Feature Summary

• Dual high-speed current feedback amplifiers optimized for broadband performance and high linearity.
• Integrated power management allowing operation in full, medium, low power, or complete shutdown modes via logic control pins.
• High output current capability enabling effective driving of low impedance loads such as 50 Ω or 100 Ω resistors.

Applications

• Home networking line drivers
• Twisted pair line drivers
• Power line communications
• Video line drivers

Procurement Notes

Verify the specific package option CP-16-23 (16-Lead Lead Frame Chip Scale Package) matches the design requirements. Confirm that the exposed thermal pad connection to ground is implemented correctly in the PCB layout to ensure proper electrical function and thermal dissipation. Ensure power supply decoupling utilizes low ESR capacitors placed close to the supply pins to maintain stability.

Selection Notes

Select this component when designing circuits that require high slew rates and wide bandwidth for driving low impedance transmission lines. The integrated shutdown feature makes it suitable for systems needing power optimization. Verify that the required closed-loop gain aligns with the recommended feedback resistor values to maintain stability and desired bandwidth characteristics.

Part Context

This part belongs to the ADA4310-1 series of dual high-current output line drivers. It is available in multiple package options including the 10-lead MSOP and the 16-lead LFCSP. The ACPZ suffix specifically denotes the 16-lead Lead Frame Chip Scale Package variant, which supports both single and dual supply configurations unlike the MSOP version.

Replacement Considerations

Direct substitutes within the same family include ADA4310-1ACPZ-R2 and ADA4310-1ACPZ-R7, which share identical electrical specifications and pinouts but differ in reel packaging quantities.
